Their excursions at first were a matter of pleasure only, but by one unexpected stroke from the sinister powers of the wild they were suddenly made necessary. Her first knowledge of the blow came when Bill entered her cabin to build the morning fire. She had not yet risen. It had always been her practice to wait till the room was snug and warm before she dressed. She was asleep when Bill came in, and aroused by his footsteps, she was aware of the fleeting memory of unhappy dreams. She couldn't have told just what they were. It seemed to her that some unseen danger had been menacing her security,--that evil and dangerous forces were conspiring and making war against her. Hidden foes were in ambush, ready to pounce forth. The danger seemed different and beyond that which she had faced every day: snow and cold and the other inanimate forces of the wild. And she was vastly relieved to hear Bill's voice calling her from sleep. But the next instant her fears returned--not the ghastly fear of evil dreams but of actual and real disaster. It wasn't Bill's usual custom to waken her. He wanted her to spend as many as possible of the monotonous hours in sleep. There was a subdued quality in his voice, too, that once or twice she had heard before. She drew aside the curtain, far enough to see his face. There was no paleness, however, nor no fear, for all that his eyes were sober. "You'd better get up as soon as you can, Virginia," he said. "We've got to take a real hunt to-day." "Hunt? After meat?" "Yes. We're face to face with a new problem. The pack came by last night--the wolf pack. As usual, when men are near, they didn't make a sound. I didn't hear them at all. And they got away with the big moose ham, hanging on the spruce. Stripped the bone clean." "Then we're out of meat?" "All except the little piece outside the door. We've been going through it pretty fast." Bill spoke true. Their meat consumption had practically doubled since Harold had come. For all his lack of physical exercise, the latter was an unusually heavy eater. "But we won't be able to find any now. The moose are gone----" "We're not very likely to, that's certain; but it won't be a tragedy if we don't. It would only be an annoyance. It's true that we've got to have more supplies to start down--I don't believe we could make it through with what we have, considering the loss of this ham--but if it's necessary I can mush over to me Twenty-three Mile cabin and get the supplies I left over there. Harold tells me he hasn't a thing in his old place. However, I can do it, if we don't happen to pick up some meat to-day." "We might track down the wolves, and get one of those----"
